Gravity Dilation Meter

A precision instrument embedded in the TARDIS console, its brass casing etched with intricate Gallifreyan symbols. The meter's needle trembles under the strain of synchronized dematerialization, its readout flickering between normal space and the warped gravity fields of Zanak. A secondary display predicts the catastrophic dilation effects of a miscalculation, glowing crimson when Romana's adjustments approach the danger zone.
